Description

PTFE  tube is divided into extruded tube and molded tube, using polytetrafluoroethylene suspension polytetrafluoroethylene resin processing.

Sodium treatment：Sodium treatmen that surface of PTFE is treated with Sodium naphthalene liquid to give its surface a special treatment, making the liquid and surface of etched PTFE tube to produce chemical reaction, tear off the surface of fluorine molecules. At this time, carbonization layer and some polar groups are left on the surface, so as to obtain activated PTFE. In this way,etched PTFE tube can be bonded  with  rubber, metal, plastic, wood, non-metal and other materials. The surface of etched PTFE tube is brown.

Advantage

1. Good temperature resistance、Corrosion resistant 、non-toxic.

2. High bonding strength, long service time, long life, strong acid and alkali corrosion resistance, not easy to peel.

3. Sodium treatment only produces effect on the surface, has no effect on the inside of PTFE tube,does not affect its basic characteristics.

4. As a result of sodium treatment of PTFE to maintain the low friction coefficient of the original material, machine operation is light, anti-climbing, small vibration.

Application

Widely used in machinery, chemical, aviation, electrical and electronic, national defense industry, cutting-edge technology, medical and health and electrical insulation and other fields.
